Care and Cleaning

Caution 

Organic solvents cause acrylic to “craze” or crack. Clean all acrylic

systems with warm water and a mild detergent. Do not use ethanol or
other organic solvents to clean these products. Do not autoclave, bake, or
microwave your unit. Temperatures over 50°C can damage the acrylic. 

s

Note If an RNase free electrophoresis system is desired, there are various
methods to rid the system of RNA contamination. For fast and easy
decontamination, use RNase Away®*. Spray, wipe or soak labware with
RNase Away then wipe or rinse the surface clean; it instantly eliminates
RNase. RNase Away eliminates the old methods that include treatment
with 0.1% Diethyl Pyrocarbonate (DEPC) treated water and soaking in
diluted bleach. This electrophoresis system should never be autoclaved,
baked, or placed in a microwave.

Warning

DEPC is suspected to be a carcinogen and should be handled

with care.
